Manganese Dioxide

ʻO ka wehewehe pōkole:

ʻO Manganese Dioxide, kahi paʻa ʻeleʻele-ʻeleʻele, he mea molekala manganese me ke ʻano MnO2. ʻO MnO2 i ʻike ʻia he pyrolusite ke loaʻa i ke ʻano, ʻo ia ka mea nui loa o nā pūhui manganese āpau. ʻO Manganese Oxide he mea hoʻoheheʻe inorganic, a me ka maʻemaʻe kiʻekiʻe (99.999%) Manganese Oxide (MnO) Powder ke kumu maoli o ka manganese. ʻO Manganese Dioxide kahi kumu Manganese paʻa ʻole hiki ke hoʻoheheʻe ʻia i kūpono no ke aniani, optic a me nā noi ceramic.

Māhele Huahana MnO2 Nā ʻano huahana
ʻAno Manganese Dioxide C ≥75% Loaʻa iā ia nā pōmaikaʻi kiʻekiʻe e like me ka γ-type crystal structure, kahi ākea ākea nui, ka hana hoʻoheheʻe wai maikaʻi, a me ka hana hoʻokuʻu;
ʻAno ʻAno Manganese Dioxide P ≥82%
Ultrafine Electrolytic Manganese Dioxide ≥91.0% He liʻiliʻi liʻiliʻi ka nui o ka huahana (hoʻomalu pono i ka waiwai mua o ka huahana i loko o 5μm), ka nui o ka hāʻawi ʻana i ka nui o ka nui o ka nui, γ-type crystal form, ka maʻemaʻe kemika kiʻekiʻe, ke kūpaʻa ikaika, a me ka hoʻopuehu maikaʻi ʻana i ka pauka (ʻo ka ikaika diffusion he mea nui. ʻoi aku ka kiʻekiʻe ma mua o nā huahana kuʻuna ma mua o 20%), a hoʻohana ʻia i nā kala me ka saturation kala kiʻekiʻe a me nā waiwai ʻē aʻe;
ʻO Manganese Dioxide Maʻemaʻe Kiʻekiʻe 96%-99% Ma hope o nā makahiki o ka hana ikaika, ua hoʻomohala maikaʻi ʻo UrbanMines i ka manganese dioxide kiʻekiʻe, nona nā ʻano o ka oxidation ikaika a me ka hoʻokuʻu ikaika. Eia hou, ua loaʻa i ke kumukūʻai kahi mea maikaʻi loa ma luna o ka electrolytic manganese dioxide;

He aha ka mea e hoʻohana ai i ka Manganese Dioxide?

*Makemake ʻia ʻo Manganese Dioxide ma ke ʻano he mineral pyrolusite, ʻo ia ke kumu o ka manganese a me kāna mau pūhui a pau; Hoʻohana ʻia e hana i ke kila manganese ma ke ʻano he oxidizer.
*Hoʻohana mua ʻia ʻo MnO2 ma ke ʻano he ʻāpana o nā ʻokoʻa kelepona maloʻo: nā ʻāpana alkaline a me ka mea i kapa ʻia ʻo Leclanché cell, a i ʻole nā ​​​​battery zinc–carbon. Ua hoʻohana maikaʻi ʻia ʻo Manganese Dioxide ma ke ʻano he mea kūʻai ʻole a nui loa. I ka hoʻomaka ʻana, ua hoʻohana ʻia ka MnO2 kūlohelohe a ukali ʻia e ka manganese dioxide i hoʻohuihui ʻia me ka hoʻomaikaʻi nui ʻana i ka hana o nā pihi Leclanché. Ma hope mai, ua hoʻohana ʻia ka manganese dioxide (EMD) i hoʻomākaukau ʻia i ka electrochemically e hoʻonui i ka hiki o ke kelepona a me ka hiki ke helu.
* Nui nā hoʻohana ʻenehana i ka hoʻohana ʻana i ka MnO2 i nā seramika a me ka hana aniani e like me ka puaʻa inorganic. Hoʻohana ʻia i ka hana aniani e wehe i ka ʻōmaʻomaʻo i hana ʻia e nā haumia hao. No ka hana ʻana i ke aniani ʻamethyst, ke aniani hoʻomaʻemaʻe kala, a me ka pena ʻana ma ka porcelain, faience, a me ka majolica;
* Hoʻohana ʻia ka ea o MnO2 i nā ʻenehana electrotechnics, pigments, browning gun barrels, i mea maloʻo no nā pena a me nā varnish, a no ka paʻi ʻana a me ke kala ʻana i nā lole;
* Hoʻohana pū ʻia ka MnO2 ma ke ʻano he puaʻa a ma ke ʻano he mea mua i nā pūhui manganese ʻē aʻe, e like me KMnO4. Hoʻohana ʻia ʻo ia ma ke ʻano he reagent i ka synthesis organik, no ka laʻana, no ka hoʻohemo ʻana o nā alkohol allylic.
* Hoʻohana pū ʻia ʻo MnO2 i nā noi mālama wai.
